Sorry if the forum thinks this is a silly question but, when Nikon service do a replacement of D600 shutter, will it become a D610? If so, I want a new sticker, to put in front of the camera instead of the old....!

even if they fit the same shutter assembly, there are a few incremental changes between them

.5 fps increase

Apparently a quiet continuous mode (I say because some say they can't tell the difference)
